Well, that's back again - for the third time - for me, so at a /guess/ it's self-recovering to an extent.
I've flagged that up to Damaratus, but at a guess no-one's available tech-side just now to check beyond the queues & monitors (and I don't "officially" have access to browse even those anymore, so I'm not prodding the relevant URLs).
We shouldn't be that far off peak just now, but would certainly be worth checking up on if that's not been deliberately throttled for testing. No indication of that that I can see, anyhow.
Hopefully an update to follow...
